[Electroconvulsive therapy in comorbidity of treatment refractory paranoid hallucinatory psychoses with Parkinson disease].

We report the case of a 49-year-old woman with a therapy resistant paranoid hallucinatory psychosis and coexisting severe symptoms of Parkinson's disease. Over a 3-week period she received electroconvulsive therapy (ECT) 10 times, while the medication of haloperidol 8 mg/day, thioridazin 90 mg/day, metixen 17.5 mg/day and biperiden 6 mg/day was continued. There was a general improvement of the clinical picture, more pronounced for the parkinson symptomatology than for the psychotic disorder.
